- FFmpeg
- BullMQ
- Redis
- AWS S3
- Consumes video processing jobs from queue
- Handles CPU-intensive video processing outside the main API
- Transcodes videos into HLS format (m3u8 + segments)
- Generates thumbnails
- Uploads processed assets to S3
- Updates video status (PROCESSING → COMPLETED → FAILED)
- Retry mechanism for failed jobs
- Event-driven processing using Redis + BullMQ
- Decoupled from API (independent worker service)
